Double Weir Unit 1 Refurbishment

The Imperial Irrigation District is preparing to rehabilitate Unit 1, a 180 kW vertical hydraulic turbine generator at the Double Weir Hydroelectric Facility located near Calexico, California. The project aims to restore hydraulic performance, extend the equipment’s service life, and ensure continued safe and efficient hydroelectric generation by replacing components that have reached the end of their useful life. Work includes routine maintenance, repair, and in-kind replacement of degraded internal mechanical parts, a complete overhaul of the wicket gate assembly, and installation of a new stainless-steel lined runner chest, along with renewal of all associated bushings, sleeves, cartridges, and locking hardware. The original generation capacity of 180 kW must be maintained, and all activities are confined strictly within the existing facility footprint with no physical expansion or change to the historically approved site use. Major components and replacement parts will be supplied by the Original Equipment Manufacturer and installed by IID’s own hydroelectric maintenance personnel. The project is categorized as a forecast solicitation posted on July 15, 2026, under NAICS code 811310, and is currently not tied to a formal solicitation number or contract value. Environmental compliance has been established through a Notice of Exemption confirming that the project is categorically exempt from CEQA review under Sections 15301 and 15302, as it involves repair and maintenance of existing infrastructure without significant environmental impact. The place of performance is specified as Yourman Road, one mile north of Calexico, with a zip code of 92231. The point of contact for environmental compliance is Jeremy Brooks, reachable via email or phone. Despite comprehensive technical specifications and site constraints being outlined, there are no details provided regarding pricing, contract duration, inspection criteria, packaging requirements, evaluation factors, certifications, or special contractual conditions beyond environmental exemption and scope limitations.
